Promax Pedalboard CK-1

The CK-1 cranks are the high-end carbon crank offering from Promax. The race-ready carbon design maximizes strength while minimizing weight.

The high-end carbon cranks are lightweight and extremely strong.
The 30 mm chromoly axle provides increased stiffness and efficient power transfer.
